Answer:
Step-by-step explanation:
The distance between a point (x,y) and the point (-3,4) is
d1= .
The distance between a point (x,y) and the point (0,0) is
d2= .
You know what y is from the equation of the line, so substitute that, set d1=d2, and solve for x.
The given formula
Solve for y means we have to make y alone
\\
Add -10 on both sides, we get
As there is multiplication sign between r and y so to solve for y, divide both side by r
